My invention relates to anchOring devices for rails and moreparticularlyto the one piece type of anchor in which an upwardlyextending arm enters the fishing space and is Wedged in between ti 1ehadand base at one side .of the rail and a shorter upwardly extending armgrips the rail base at the other side of the rail.

One of the Objects of the-inventioh is to provide.a rail anchor of thisgeneral type which may be easily'and 'efliciently manufactured, readilybrought'toits preIiminarypost tion for application on th e rail; and,When applied to the rail will be in i tsProper opera= tive position,firmly grip boththe head and base of the rail and be so securely held inits operatie position on the.rail that it will not be accidentaliydis1odged or loosened but may, when desired, be quiekiy remoVed.

, Other objects of the invention are to pro- Vide an anchor of the abovegneral character in WhiCh the two uiqwardiy extending arms are, duringthe application of the anchor to the rail, forced more widely apartthair herst0fore, with corresponding increase in the gripping pressureeXerted on the rail by. the resilienoy Of the anchor; to .proVidemaximum gripping pressure upon the head of the rail near thedges of thehead:engaging end of the, anehorj and to provide means for indicatingthe proper anchor on' the rail. i 7 s The invention has for furtherobjects Such other new and improved arrangements and constructions asWill be hereiri 2ifter,described and clainied for carrying ont the abovestated objects.

The invention is illustrated intwo embodiments in the accompanyingdrawings, whrein {Figure 1 is an elevation, with the rail in section,.of a rail anehor 'construeted in ac- Cordance with nov invention in itsoperative position on the rail.

anchor is designated by D and is 15rferabi iormed ofa steei bar benttoprovidc a' long arm E, corresponding in 'shape roughi to the crosssect on of the Ordinary fishb ar or fishplate, and a shorter arm' F. Thelong ar1n 13 is made to fit i nto the fishing spacex v betwecn the headand base of therailand to be wedged therein.and'thesht arr n F isprovzded to engage and gripflthe rail base B at the.side of the railopposite to that engaged by the long arm B. 'The arrns E and F are 'soformed and related to each other. 011 the anchor D that, in theunstresised condition of the anchor, they are doser together than theyare in the Stressed condition of the anchor when it is in its appliedoperativeposition on the rail so that they must be forced aWaythe onefrom the other as the'anchor D is forced from1ts nitial or prehminarypositionshown in Figure 4 ,to its'*final oPerativeyposition shown inFigure 1. Thedotted lines in Figure 1 show theimstressed form and thefull fines in.the saine figure the stressed .f0rm of the anchoiD.

The end of the long arrn Ehas its edges rnadc thinner than its media1portion by forniing dpressions G, preferabiy by forging or pressing themate'ri al of the bar-cf whiclithe anchor D is made, thus flatteningthebar at its edg;es, forming Slight projections.

1n applying anohors of this character to the -rail the longerarm mnstbebroughtto an inclined position in the fishing space' between the head Aand base B o f'the'rai1- with the'body undernath the'rail base 18 sothat the shQrter arm F may 'be broaght up by I the rail base B at theother side of the rail.

This position is illustrated in Figure 3,and it Will be scn-that thedistance which the two arins E and F may be apartin the un stressedcondition of the anchor D is determined bythe Contact of one of theupper corners on the longer arm E withthe web of the ra1l and thecontact of one of the corners of the shorter armFwith tl1e opposite edgeof the rail base B. It is desirable to have the two arrns E and F asclose together aspos- 7 sible and still permit the anchor D to Inc rbrought to the initial position shoivn in Figure 4 because the extent towhich the arme are Spread apart as'the anchor D is forccd from, itsinitial position to the final operative position det rmines the pressureex erted by the anchor D upon the rail when in its st'ressed conditionin operative' position on the rail. Theformingofthe dpressions G on theupper end of the longer ar1nE With a surface H, below the projectionsI,which willengagethe lower corner ofthe head A of the rail When theanchor is in its preliminary position on the rail as illustrated inFigure 4.

, The fiattening of the upper end of the shorterarm F further increasesthe distance between the upper corners of the two arrns E and F, Whihdetermines the ability of the anchor D tobe passed by the rail base B tothepreliminary position shown in Figure 4, and thus, in connection Withthe depresSionsG at the upper end of the arm E, prov1desa construction1n' Which the arms E and F are, in the unstressed-condition of theanchor D, doser together 'thanlwould otherwise be possibleand theshorter arm thus may be made. longer than would other wise be possible.

T0 apply the anchor D t0 a rail it'is, after passing the short arm bythe rail base as illustrated in Figure -3, moved along the rail towardatic, in the direction in which the rail tends to creep (indicztted' bythe arrow in Figure2), and then brought toth preliminary position shown,in Figure 4 with the surface H on,theflupper end of the longer x arm Eengagmg the under. corner of the ra1l head A and thefinner face of thesliorter ar1n F ngaging the upper corner at the 'other side of the railbase B.

f The anchor D is then forcedto the final operative position. on therail, as shown in Figures land 2, bydriving the longer'arin E into thefishing space between the head A and base B of the rail and by drivingthe shorter arin F downward by blows of a hamrner indicated by the-arrowin Figure 4. This' forcing of the anchor D into operative posit1on spriads thearms and F apart, the

shorter aifim F riding on the upper corner of V "the rail base B in theearly stages of the move ment,thenthe corner -O riding on the verti-'cal edge of the rail base until the surface L slips uncer and contactswith the lower cor ner of the rail base B at whichtime the sur face Kmaycontzrct with the vertical edge of the rail base, as shown in Figure1, the forging of the surface K has been. such that its plane isVertical at this tinue. This is not essential. The providing of"the twvosur faces K and L has the advantage ofindicating unf ailingly to theperson applying the anchor its correct operative position on the rail.Thelonger arm E, during this forcing of the anchor D to operative'position, is wedged into the fishing opening betweenthe head A and baseB the surface H riding on thei1nder side of the rail head A until theprojections I 'come into engagement with the surface of the under sideof therail head A. The projections I inthe final operativc :f'
